Mathematical Methods in the Applied Sciences, EarlyView.The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.

Spectral Submanifolds of Delay Systems: Control in Continuous and Discrete Time
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This paper presents both continuous‐time and discretization‐based approaches for constructing spectral submanifolds (SSMs) for time delay systems. The continuous‐time approach built upon sun–star calculus, reformulates the governing delay differential equation (DDE) as an operator differential equation (OpDE).

Reductive Dechlorination of DDE to DDMU in Marine Sediment Microcosms
, 1998 DDT is reductively dechlorinated to DDD and dehydrochlorinated to DDE; it has been thought that DDE is not degraded further in the environment. Laboratory experiments with DDE-containing marine sediments showed that DDE is dechlorinated to DDMU in both ...

The limited (but relevant) role of the doctrine of the double effect in the Just War Theory
Ethics & Global Politics, 2017 My focus in this paper is the use of the doctrine of double effect (DDE) in the context of Just War Theory. Different versions of DDE have different degrees of plausibility. Two distinctions are crucial.

Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations
Journal of Field Robotics, EarlyView.ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).

Delay differential equation models for real-time dynamic substructuring [PDF]
, 2005 Real-time dynamic substructuring is a testing technique that models an entire system through the combination of an experimental test piece, representing part of the system, with a numerical model of the rest of the system.
